403 Forbidden error while adding/updating meta fields to existing image by Prashant Bhure

Hi,

I am updating my existing images on the shopify store but for some reason I am getting 403 error.

Could anybody please help me.

I have the requests as follows.

Update existing Image Meta field.

https://ShopName.myshopify.com/admin/images/<ImageId>/metafields/<MetaFieldId>.json

     {

     "metafield": {

     "id": MetaFieldId,

     "value": "Basketball",

     "value_type": "string"

     }

     }

Add new  Image Meta field to existing Image.

     https://ShopName.myshopify.com/admin/images/<ImageId>/metafields.json

     {

     "metafield": {

     "description": "PictureAltText",

     "namespace": "tags",

     "key": "alt",

     "value": "Basketball",

     "value_type": "string"

     }

     }

Thanks
